Development of Tau Microdialysis as a Method to Study Tau Metabolism, Pathophysiology and Response to Treatment

The hypothesis of this proposal is that a method can be developed to measure tau levels in the extracellular space of the brain (interstitial fluid–ISF) and that assessment of ISF tau in both normal mice as well as a variety of animal models that develop AD pathology will provide new insights into tau metabolism and the relationship between Aβ and tau in AD. If this method development is successful, it has a chance to tell us more about the pathophysiology of AD as well as a provide a novel way to screen for new AD treatments.
